</form>`

 function add(Request $request){
    $request->file('image')->store('public');

}

Answer 1

你的函数应该是这样的：

public function add(Request $request)
 {
     request()->validate([
         'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
     ]);
     $imageName = time().'.'.request()->image->getClientOriginalExtension();
     request()->image->move(public_path('images'), $imageName);
     return back()->with('success','You have successfully upload image.');
}
